(1-8. Control device 9)
As illustrated in FIG. 13, the control device 9 includes a control unit 88 and a storage unit 89. As will be described later, the control unit 88 refers to the data stored in the storage unit 89 on the basis of prescription data input from the server 90 via a LAN or the like and input signals from the sensors. The chemical liquid bottle 2 mounted on the bottle mounting portion 45 is rotated by driving and controlling the components, and the chemical liquid bottle 2 is rotated to agitate the stored chemical liquid. A series of dispensing processes such as pouring the chemical solution into the bottle 6, diluting the chemical solution with dilution water, washing the first nozzle 51, and drying are controlled.

(2. Operation)
Next, the operation of the dispensing apparatus having the above configuration will be described.

When the prescription data is received from the server (step S1), the medicinal solution bottle 2 filled with the medicine (the first medicine when there are a plurality of medicines) included in the prescription data is specified (step S2). In this case, when the chemical liquid bottle 2 is mounted on each rotation support portion 27 of the bottle support portion 3 in advance, the medicine to be stored and the rotation support portion 27 to be mounted are associated with each other. This is performed based on the data stored in the storage unit 89.

If the chemical solution bottle 2 is specified, it is determined whether or not stirring is required before the contained chemical solution is dispensed (step S3). This determination uses data stored in the storage unit 89 in advance as information (chemical solution information) regarding the chemical solution stored in the chemical solution bottle 2. If it is determined that the agitation is necessary, the rotation support portion 27 to which the corresponding chemical liquid bottle 2 is attached is positioned at the rotation position by driving the drive motor 32 and rotating the annular support body 26 ( Step S4). Then, by driving the first motor 54 of the rotation drive unit 4, the drive gear 58 is advanced and meshed with the driven gear unit 49 of the rotation support unit 27 (step S5). Subsequently, by driving the second motor 59, the rotation support portion 27 is rotated, and the chemical liquid bottle 2 attached thereto is moved between the attachment position and the attachment / detachment position (step S6). In this case, the rotation direction of the chemical liquid bottle 2 is the inside of the chemical liquid bottle 2 arranged on substantially the same circumference, that is, a dead space where no parts are arranged. Therefore, the chemical solution in the chemical solution bottle 2 can be agitated without increasing the size of the apparatus. And since the chemical | medical solution bottle 2 is rotated until it turns upside down, the accommodated chemical | medical solution can fully be stirred.

If the chemical liquid in the chemical liquid bottle 2 is agitated, the drive motor 32 is further driven to rotate the annular support 26, and the corresponding chemical liquid bottle 2 is positioned at the dispensing position (step S7). A patient bottle 6 to be poured out by an operator in advance is set at the dispensing position. For example, the patient bottle 6 may be set by automatically selecting an appropriate size and displaying it on the display 14 based on the prescription data. In the set bottle 6 for patient, the mouth 46 is detected by the detection sensor, and the second elevating motor 62 is driven and controlled based on this detection signal, so that the placing plate 64 is moved up and down to raise the patient bottle 6. Is positioned at the dispensing standby position (step S8), and the chemical solution dispensing process is started (step S9).

In the chemical solution dispensing process, the arm motor 42 is driven to press-contact the second nozzle 52 to rotate the drive arm 41 from the clamping position to the open position (step S21). Then, the first nozzle 51 is fully opened (step S22). Further, the compressor 87 is driven to supply air into the chemical liquid bottle 2 (step S23), and the internal pressure is increased, thereby smoothing out the chemical liquid.

In this case, the first nozzle 51 is fully opened and air is supplied into the chemical liquid bottle 2 to determine how much chemical liquid is discharged per unit time for each chemical bottle containing different types of chemical liquids. A database is prepared in advance by experiments or the like and stored in the storage unit 89. And based on this database, the chemical | medical solution amount poured out in the bottle 6 for patients is estimated.

Thereafter, by reaching the set amount before reaching the desired amount of the chemical solution (step S24), the drive arm 41 is rotated to the intermediate position (step S25), and the amount of the dispensed chemical solution is suppressed. Here, based on the weight of the chemical liquid bottle 2 detected by the weight detection sensor 65, the chemical liquid becomes a desired amount determined by the prescription data (the volume of the chemical liquid converted from the weight based on the specific gravity of the chemical liquid). (Step S26), the drive arm 41 is rotated to the clamping position, and the dispensing of the chemical solution is stopped (Step S27).

If the chemical solution pouring process is completed, it is determined whether or not the diluting water needs to be poured (step S10). If it is determined that dilution water injection is necessary, the dilution water injection process is started (step S11).

In the dilution water injection process, the mounting plate 64 is lowered to position the chemical bottle 2 at the dilution water injection position based on the detection signal from the lift position detection sensor 70 (step S31). And the rotation arm 76 of the dilution water injection | pouring part 7 is rotated, and the injection port 76b of the injection tube 74 is located above the opening part 46 of the bottle 6 for patients (step S32). Then, a desired amount of dilution water is injected based on the prescription data in the same manner as in the case of the chemical solution (step S33).

When the chemical solution dispensing process and the dilution water injection process to be performed as appropriate are completed, the drive motor 32 is further driven to rotate the annular support 26 to move the corresponding chemical solution bottle 2 to the cleaning position (step S12). The process is started (step S13).

In the cleaning process, since the lower end opening of the first nozzle 51 is located above the cleaning nozzle 83, the second tube pump 86 is driven to eject the cleaning water in the cleaning water tank 18 from the cleaning nozzle 83 ( Step S41). Thereby, the lower end portion of the first nozzle 51 is washed. The waste water after washing flows to the center of the bottom by the washing dish 80 and is collected from the waste water outlet 81 to the waste water tank through the waste water tube 82.

When the cleaning of the first nozzle 51 is completed, the driving motor 32 is further driven to rotate the annular support 26 and move the chemical bottle 2 to the drying position (step S42). Then, the compressor 87 is driven to blow air to the first nozzle 51 via the air supply nozzle 84, and the attached cleaning water is dried (step S43).

Hereinafter, in the same manner, a dispensing process for each chemical solution included in the prescription data is executed. When the dispensing process for all the chemicals included in the prescription data is completed, the same process is performed for the next prescription data.

As described above, according to the dispensing device according to the embodiment, the space at the central portion surrounded by the attached chemical liquid bottle 2 that was originally a dead space is used for the stirring of the chemical liquid in the chemical liquid bottle 2. It can be used effectively as a moving area. For this reason, a chemical | medical solution can be stirred, without enlarging an apparatus. Further, since the chemical liquid bottle itself is rotated, the chemical liquid can be sufficiently stirred. In addition, since the rotation drive unit 4 need only be provided at one place, the structure is not complicated and the cost is not increased.

The present invention is not limited to the configuration described in the first embodiment, and various modifications can be made.

In the first embodiment, the amount of the chemical liquid poured out from the chemical liquid bottle 2 into the patient bottle 6 is adjusted using a pinch valve, but the following configuration is also possible.

That is, two types of tube pumps, one having a large delivery flow rate per unit time and one having a small delivery flow rate (may be three or more types having different delivery flow rates per unit time), are prepared. However, only one motor (stepping motor, servo motor, etc.) is used and connected to either one of the tube pumps so that power can be transmitted. Then, when the drug solution is poured out from the drug solution bottle 2 into the patient bottle 6, a tube pump having a large delivery flow rate is used until the set value before reaching the desired amount determined by the prescription data, and the set value is reached. For example, switch to a tube pump with a small delivery capacity. As a result, the dispensing process is performed by using a plurality of tube pumps without increasing the number of expensive motors, so that the dispensing error can be suppressed while realizing the optimum dispensing speed. . In addition, the cost is not increased so much.

In addition, by using the opening / closing cam 91 shown in FIGS. 25 (a) and 25 (b), the tube 18a is opened and closed by the pressing member 92 that rotates about the support shaft 92a, and a fixed amount (for example, 5 ml) is used for the patient. You may make it supply a chemical | medical solution in the bottle 6. FIG. That is, the opening / closing cam 91 has protrusions 91a formed at equal intervals in the circumferential direction. The pressing member 92 is biased by a spring 93 so as to contact the outer periphery of the opening / closing cam 91. When the opening / closing cam 91 is rotated, as shown in FIG. 25A, when the opening and closing cam 91 is rotated, the pressing member 92 rotates counterclockwise about the support shaft 92a when pressed by the projections 91a. When 18a is deformed and closed, as shown in FIG. 25 (b), when it comes into contact with the outer peripheral surface 91b, the tube 18a is opened by rotating clockwise around the support shaft 92a. At this time, since the rotation speed of the opening / closing cam 91 is constant, the amount of chemical solution dispensed when the tube 18a is opened by one protrusion 91a is constant.

In the first embodiment, the tubes 18a, 52a and the like are used as they are. However, if a coil spring is provided on the outer periphery, for example, the tubes 18a, 52a and the like are moved when the chemical bottle is rotated. It is preferable in that it can be prevented from being bent or stretched and its durability can be improved.

(Second Embodiment)
FIG. 18 shows a dispensing device according to the second embodiment. Since this dispensing apparatus basically has the same configuration as that according to the first embodiment, the description of the same configuration is omitted, and the difference will be described below.

The bottle support unit 101 includes a support base 102 and a guide member 103 fixed to the support base 102.

The support base 102 includes a ceiling portion 104 and a pair of opposing side surface portions 105 extending downward from both side edge portions (a side surface portion located on the front side in FIG. 19 is not shown). A circular opening 106 is formed in the ceiling 104. A bottle mounting portion 107 is fixed to the upper surface of the ceiling portion 104. The bottle mounting portion 107 is made of an elastic material such as rubber, and includes a flat portion 108 screwed to the upper surface of the ceiling portion 104 of the support base 102 and a cylindrical portion 109 formed on the upper surface thereof. A first flow path connecting portion 110 and a second flow path connecting portion (not shown) are formed in the flat portion 108 in a region surrounded by the cylindrical portion 109, and the flat portion 108 communicates vertically. Yes. A female screw is formed on the inner peripheral surface of the cylindrical portion 109, and a male screw formed at the mouth of the chemical liquid bottle 2 can be screwed. One end of the tube 112 is connected to the lower end of the first flow path connecting part 110. Similarly to the above-described embodiment, the second flow path connecting portion is connected to the upper end portion of the first nozzle 51 extending into the chemical bottle 2 attached to the cylindrical portion 109, and to the lower end portion of the tube 52a. Yes.
The bottle mounting portion 107 preferably has at least the second nozzle 52 integrated (the first nozzle 51 may be integrated) and is detachable from the support base 102. According to this, since the bottle mounting part 107 integrated with the second nozzle 52 can be attached to the mouth of the chemical liquid bottle 2 in advance, the chemical liquid can be attached by mounting the chemical liquid bottle 2 as described above. The operation of inserting the second nozzle 52 into the inside of the bottle 2 becomes unnecessary, and the mounting operation to the bottle support portion 101 can be performed quickly and smoothly. Further, when the chemical bottle 2 is removed, there is no concern that the second nozzle 52 is exposed and the chemical liquid remaining in the second nozzle 52 leaks out.

A pressure sensor (not shown) is provided in the middle of the air path from the first nozzle 51 to the pump 73 (for example, in the middle of the tube 52a), and the air pressure in the chemical liquid bottle 2 is detected. The pump 73 is driven and controlled based on the value detected by the pressure sensor so that the air pressure in the chemical liquid bottle 2 is maintained at a predetermined value. According to this, the air pressure in the chemical solution bottle 2 becomes too high, the amount of the chemical solution supplied to the patient bottle 6 increases per unit time, and the detection error by the weight detection sensor 65 does not occur. Further, by increasing the air pressure according to the viscosity of the chemical liquid stored in the chemical liquid bottle 2, there is no possibility of defective discharge. Furthermore, it is possible to detect whether or not air leakage has occurred, for example, the pressure detected by the pressure sensor does not increase even though the rotational speed of the pump 73 is increased.
The adjustment of the air pressure in the chemical liquid bottle 2 based on the value detected by the pressure sensor may be changed according to the chemical liquid amount. In this case, the amount of the chemical solution in the chemical solution bottle 2 is calculated based on the detected amount of the chemical solution based on the detection value of the weight detection sensor 65, or the discharged chemical solution is directly detected by the flow sensor, and the obtained discharge amount Is obtained by subtracting from the initial amount of the chemical solution in the chemical solution bottle 2. According to this, the remaining amount of the chemical liquid in the chemical liquid bottle 2 is reduced, and it is not difficult to discharge the chemical liquid due to its own weight, and quick dispensing can be performed to the end.

Further, as shown by a two-dot chain line in FIG. 19, a rotating piece 113 is supported on the other side surface portion (side surface portion opposite to the side surface portion 105 to which the guide member 103 is fixed) of the support base 102. It is attached so as to be rotatable around 113a. The rotating piece 113 has a substantially fan shape, and a linear portion extending in the radial direction from the support shaft side is bent in a direction orthogonal to form a contact portion.

The guide member 103 has an arcuate guide groove 114 formed from the upper end to the lower end at the center of the side surface. Guide pieces 115a and 115b project from both ends of the guide groove 114, respectively. A tube 112 described later is disposed in the guide groove 114. A through hole 103 a through which the tube 112 is inserted is formed on the lower side of the guide member 103. A first pressing member 117 is attached to the vicinity of the through hole 103a so as to be rotatable about a support shaft 117a. Further, the guide member 103 is fixed with a support guide 116 for guiding a support shaft 138a which is a rotation center of a cam member 139 and a second pressing member 145, which will be described later.

The first pressing member 117 includes a thin upper portion 118, a thick intermediate portion 119, and a lower portion 120 that extends from one side of the intermediate portion 119 and is provided with a support shaft 117a. On both sides of the upper portion, first protrusions 121 and second protrusions 122 are formed at two positions in the width direction, respectively. A rotation piece 113 (described later) and a protrusion 143 of the cam member 139 are in contact with and pressed against the protrusions 121 and 122, respectively. A concave portion 123 that is recessed from the upper portion 118 and the lower portion 120 is formed at the side edge portion of the intermediate portion 119. The recess 123 is formed with a first pressing portion 124 that protrudes in the same direction as the support shaft 117a. The first pressing part 124 plays a role of pressing the tube 112 and closing the flow path, or separating and opening the tube 112. A locking hole 125 is formed in the intermediate portion 119, and a coil spring 126 is locked between the locking hole 125 and a locking shaft 103 b fixed to the guide member 103. Accordingly, the first pressing member 117 is urged counterclockwise in FIG. 19 around the support shaft 117a, and is positioned at the closed position where the first pressing portion 124 closes the flow path of the tube 112. .

As shown in FIG. 18, an operation unit 127 is attached to the apparatus main body 1.
The operation unit 127 is provided at the pouring position of the apparatus main body 1 and includes a mounting frame 128 and a sliding member 129 slidably supported on the mounting frame 128 as shown in FIG. is there.

The mounting frame 128 has a rectangular frame shape, and two sliding rails 130 are juxtaposed between a pair of opposing side walls. The sliding motor 131 is attached to the outer surface of one of the other set of side walls of the mounting frame 128, and the rotation motor 132 is attached to the outer surface of the other side wall.

The sliding member 129 is slidably attached to the sliding rail 130 via the bush 133. Then, when the sliding motor 131 is driven to rotate forward and backward, the sliding member 129 is moved forward and backward through the pinion 131a and the rack 131b provided on the rotating shaft, respectively. Positioning is possible. The operating position and the standby position are specified by detecting a part of the detected plate 134 attached to the upper surface of the sliding member 129 by the first sensor 135 and the second sensor 136 provided on the side surface of the attachment frame 128, respectively. The positioning can be performed by driving and stopping the sliding motor 131. As shown in FIG. 23, the sliding member 129 includes a top plate and side plates extending downward from both side edge portions thereof, and a mounting plate 138 extending further forward is fixed to the side plate. A cam member 139 and a second pressing member 145 are integrally attached to the attachment plate 138 so as to be rotatable about a support shaft 138a.

The cam member 139 is made of a metal plate, and is supported on the mounting plate 138 so as to be rotatable forward and backward about the support shaft 138a. A first pulley 140 is provided on the support shaft 138 a, and power is transmitted by a belt 142 that extends between the first pulley 140 and a second pulley 141 that is rotationally driven by a rotation motor 132. On the outer peripheral edge of the cam member 139, an extended region is formed that bulges in the outer diameter direction within a predetermined angle range from the support shaft 138a that is the rotation center. In FIG. 19, a part of the extended region on the counterclockwise direction side is a protruding portion 143 that further protrudes. The protrusion 143 presses the second protrusion 122 of the first pressing member 117 when the cam member 139 rotates counterclockwise about the support shaft 138a, and the first pressing member 117 is centered on the support shaft 117a. And rotate clockwise. In addition, a pressing roller 144 is attached to a part of the extended region on the clockwise direction side. The pushing roller 144 pushes and turns the turning piece 113 when the cam member 139 is turned clockwise about the support shaft 138a. Thereby, the rotating piece 113 presses the first protrusion 121 of the first pressing member 117, and the first pressing member 117 is rotated clockwise about the support shaft 117a.

The second pressing member 145 has a configuration in which a pressing roller 147 is rotatably attached to a support piece 146 fixed to the cam member 139 as shown in FIG. The thickness of the pressing roller 147 is set to be slightly smaller than the width dimension of the guide groove 114 of the guide member 103. When the cam member 139 is rotated, the pressing roller 147 is also rotated around the support shaft 138a together with the cam member 139. The support shaft 138 a is guided by a support shaft guide 116 fixed to the guide member 103. Therefore, the rotation trajectory of the pressing roller 147 can be set to a position along the guide groove 114 with high accuracy. Then, while the pressing roller 147 moves through the guide groove 114, the tube 112 disposed therein is pressed to maintain the flow path in a closed state.

As shown in FIG. 18, a fall prevention member 148 supported by a plurality of support bars (not shown) protruding downward is attached to the ceiling surface of the apparatus body 1. This overturn prevention member 148 is formed by cutting out a part of the annular body into a substantially C shape, and reliably prevents the chemical solution bottle 2 arranged in an annular shape from accidentally falling over. Further, the notch portion is located just at the rotation position, and the rotation of the chemical liquid bottle 2 is allowed.

In the rotation of the chemical liquid bottle 2, magnets are provided at two positions on the side surface of the driven gear portion 49, and the rotation range of the chemical liquid bottle 2 is regulated by detecting the position of each magnet with a sensor (not shown). It is preferable to do this. Here, from the initial position where the chemical liquid bottle 2 is turned upside down, the inside of the fall prevention member 148 is rotated through the notch, and beyond the position directed vertically downward to the attaching / detaching position directed obliquely downward on the front side of the apparatus (about It can be rotated (within a range of 200 °). Since the chemical solution bottle 2 can be attached and detached while being directed obliquely downward at the attachment / detachment position, the workability is excellent.

Moreover, since the rotation of the chemical liquid bottle 2 is performed by detecting a magnet provided in the driven gear portion 49, there is no electrical component provided on the annular support 26 to which the chemical liquid bottle 2 is mounted. Therefore, the electric wire for power supply to the annular support 26 side is not required, and the rotation range of the annular support 26 is limited to the range of one rotation each in the forward and reverse directions as in the configuration of the first embodiment. There is no. That is, the restriction on the rotation range of the annular support 26 can be eliminated. The rotation of the annular support 26 may be managed based on detection signals from the encoder 33 and the origin sensor.

The operation of the dispensing apparatus according to the second embodiment is substantially the same as that according to the first embodiment, but the stirring process when stirring the chemical liquid stored in the chemical liquid bottle 2, and the chemical liquid bottle 2 To the patient bottle 6 is different from the dispensing process.

In the agitation process, the chemical solution bottle 2 can sufficiently agitate the chemical solution and minimize the rotation range to shorten the agitation time.

That is, by tilting the chemical solution bottle 2 from the horizontal position so that the bottom surface is located on the upper side from the inner volume, the cross-sectional area, and the dose of the stored chemical solution, the liquid surface position is the center position of the bottom surface. An inclination angle exceeding (the vertical center position when the chemical liquid bottle 2 is set to the horizontal position) is calculated. And the chemical | medical solution bottle 2 is rock | fluctuated between the calculated inclination angle and the inclination angle in the position where this inclination angle is symmetrical with respect to a horizontal surface. Thereby, the chemical | medical solution in the chemical | medical solution bottle 2 can be fully stirred. Further, the swing range does not become larger than necessary, and the stirring time can be shortened.

If the amount of the chemical solution stored in the chemical solution bottle 2 is less than half, the above condition is satisfied only by placing the chemical solution bottle 2 in the horizontal position. Therefore, the rotation angle is set before the chemical solution amount becomes less than half. A minimum fixed value may be used.

Further, the rotation range can be determined not only by the liquid level position of the chemical liquid on the bottom surface of the chemical liquid bottle 2, but also by the liquid level position on the side surface of the chemical liquid bottle 2. Further, by experiment, the amount of the chemical solution stored in each chemical solution bottle 2 may be changed to determine the minimum turning range in which it is determined that the chemical solution can be sufficiently stirred.

In the dispensing process, as shown in the flowchart of FIG. 24, the sliding motor 131 is driven to advance the sliding member 129 (step S51). Then, based on the detection signal from the first sensor 135 (step S52), the driving of the sliding motor 131 is stopped (step S53), thereby positioning the sliding member 129 at the operating position. At this time, the support shaft 138 a provided on the mounting plate 138 of the sliding member 129 is guided by the support shaft guide 116, and the cam member 139 and the second pressing member 145 are accurately positioned with respect to the guide member 103.

Subsequently, the cam member 139 is rotated in the clockwise direction in FIG. 19 by forwardly driving the rotation motor 132 (step S54). Accordingly, the pushing roller 144 provided on the cam member 139 presses the rotating piece 113, and the rotating piece 113 rotates counterclockwise about the support shaft 113a. The rotating piece 113 presses the first protrusion 121 of the first pressing member 117, and the first pressing member 117 rotates clockwise about the support shaft 117a. As a result, the first pressing portion 124 of the first pressing member 117 is separated from the tube 112, and the chemical solution in the chemical solution bottle 2 flows out to the patient bottle 6.

The supply of the chemical solution to the patient bottle 6 is performed until a predetermined dispensing amount (for example, a value 20 ml smaller than the dispensing amount) immediately before the dispensing amount obtained from the prescription data is reached. Here, the dispensing is continued until the weight of the drug solution in the patient bottle 6 obtained by subtracting the weight of the patient bottle 6 from the weight detected by the weight detection sensor 65 reaches the predetermined dispensing amount. (Step S55). However, based on the outflow amount of the chemical solution per unit time when the tube 112 is opened, the dispensing may be continued until the time when the predetermined dispensing amount is expected to be reached (the maximum dispensing process is described above). ).

When the predetermined dispensing amount is reached, the rotation motor 132 is driven in reverse (step S56), and the cam member 139 and the first pressing member 117 are rotated counterclockwise. Accordingly, the first pressing member 117 is released from the pressing force received from the pressing roller 144 provided on the cam member 139 via the rotating piece 113, and returns to the closed position by the biasing force of the coil spring 126.

Then, the pressing roller 147 of the cam member 139 reaches the guide groove 114 formed in the guide member 103 as shown in FIG. 20, and presses the tube 112 to close the flow path. Thereby, in the tube 112, the chemical | medical solution will be temporarily stored in the restriction | limiting area | region between the closed positions by the 1st press part 124 and the press roller 147. FIG. Here, the amount of the chemical stored in this restricted area is 5 ml.

Subsequently, as shown in FIG. 21, the protrusion 143 of the cam member 139 presses the second protrusion 122 of the first pressing member 117, and the first pressing member 117 rotates from the closed position to the open position. Thereby, the chemical | medical solution stored in the restriction | limiting area | region is discharged | emitted in the bottle 6 for patients. During this time, the pressing roller 147 moves in the guide groove 114, and the tube 112 is maintained in the closed state. When the pressing roller 147 moves away from the guide groove 114, the pressing state by the protruding portion 143 of the cam member 139 is released, and the first pressing member 117 returns to the original closed position.

In the same manner, the rotation of the cam member 139 is continued to temporarily store the chemical solution in the restriction region, and sequentially supply a certain amount of the stored chemical solution to the patient bottle 6 (above, Small volume dispensing process).

At this time, the weight is detected by the weight detection sensor 65 in the bottle mounting portion 60 on which the patient bottle 6 is mounted (step S57). Then, based on the weight of the chemical solution in the patient bottle 6 obtained by subtracting the weight of the patient bottle 6, the cam member 139 is obtained until a desired dispensing amount based on the prescription data is obtained (step S <b> 58). Then, the chemical solution is supplied into the patient bottle 6 by a certain amount.

Thereafter, when a desired amount of chemical solution is dispensed into the patient bottle 6 (step S58: YES), the rotation motor 132 is stopped (step S59) and the sliding motor 131 is driven in reverse (step S59). S60) Based on the detection signal from the second sensor 136 (step S61), the sliding motor 13 is stopped (step S62), and the sliding member 129 is moved to the standby position.

Thus, according to the dispensing process, the tube 112 is fully opened and dispensed at a high speed until just before the desired dispensing amount is reached, and thereafter, a certain small amount is dispensed. Thereby, the supply amount of the chemical solution into the final patient bottle 6 can be made stepwise by small amounts, and measurement errors due to the weight detection sensor 65 can be suppressed. In addition, since a certain amount of dispensing is performed only by a mechanical structure that only rotates the cam member 139, the configuration can be simplified and manufactured at low cost.

In the dispensing process, 5 ml is dispensed at the final stage. However, the dispensing amount is not limited to this, and can be freely changed according to the type of chemical solution, dispensing accuracy, and the like. Can do. In this case, what is necessary is just to adjust the chemical | medical solution quantity which can be stored in a restriction | limiting area | region by utilizing the tube 112 from which an internal diameter differs, or changing the positional relationship of the press roller 147 and the 1st press part 124.

In each of the above embodiments, the stored chemical liquid is agitated by rotating the chemical liquid bottle 2, but the entire dispensing apparatus is vibrated or the forward / reverse rotation of the annular support 26 is performed in small increments. You may make it carry out by repeating.

Further, the supply of the chemical solution into the patient bottle 6 may be performed by a user operating a not-shown operation button so that a certain amount is supplied or continuously.

In the second embodiment, the second pressing member 145 is driven to rotate in the forward and reverse directions. However, for example, the following configuration is also possible only by driving in the forward direction. However, this is only an example, and various modifications are possible.
That is, when executing a small amount dispensing process, the second pressing member 145 is driven to rotate forward in the same manner as in the second embodiment. Thereby, the protrusion part 143 of the cam member 139 presses the 2nd protrusion 122 of the 1st press member 117, the 1st press member 117 rotates, and the press state by the 1st press part 124 is cancelled | released. Further, the pressing roller 147 rolls on the guide groove 114 while maintaining the pressing state of the tube 112. As a result, the chemical solution stored in the tube 112 is dispensed by the pressing roller 147 and the first pressing portion 124 of the first pressing member 117. In the same manner, the tube is repeatedly pressed and released by the first pressing member 117 and the second pressing member 145, and the chemical solution is dispensed by a certain amount. Further, when the maximum dispensing process is executed, the second pressing member 145 is separated from the tube 112 via the mounting plate 138. At this time, along with the separation operation of the second pressing member 145, the second protrusion 122 is pressed by the protruding portion 143 of the cam member 139 that moves together with the second pressing member 145 to rotate the first pressing member 117. It is necessary to release the pressing state by the first pressing portion 124. Thereby, the flow path of the tube 112 is fully opened, and the chemical solution is continuously dispensed. In addition, according to the said modification, the components used at the time of reverse rotation, such as the 1st protrusion 121 and the rotation piece 113, become unnecessary.

In the second embodiment, the small-quantity dispensing process and the maximum dispensing process are performed by the first pressing member and the second pressing member. However, the following configuration is also possible. .

That is, FIG. 26 illustrates a pressing member in which the pressing rollers 151 and 152 are rotatably provided at two positions (a 180-degree symmetrical position) on the outer periphery of the support disc 150.
When performing a small amount dispensing process, the tube 112 is pressed by the pressing rollers 151 and 152, and the support disc 150 is rotated. As a result, the chemical solution stored between the pressing rollers 151 and 152 is moved downwardly from the tube 112 by the pressing roller 151 positioned on the lower side, and the pressing roller 152 positioned on the upper side moves to the tube 112. It is discharged by making a circular motion while maintaining the pressed state along. In the same manner, the circular motions of the pressure rollers 151 and 152 are continued, and the chemicals stored between the pressure rollers 151 and 152 are sequentially discharged.
When executing the maximum dispensing process, the pressure rollers 151 and 152 are separated from the tube 112 via the mounting plate 138, and the flow path is fully opened.

It can be made to. In addition to the parts functioning as the interlocking members, the first pressing member 223, the second pressing member 254, and the like constitute a chemical solution discharging mechanism.

The operation of the dispensing apparatus according to the third embodiment configured as described above is different from the above embodiments in the following points. Only the differences will be described below.

The plug member 218 is attached to the mouth of the chemical liquid bottle 2. That is, the air nozzle 220 is inserted from the mouth portion of the chemical liquid bottle 2 and covered with the plug body 219, and the mouth portion is disposed in the recess 224 of the plug body 219. Then, the bottle stopper 227 is slid, and the stopper member 218 is fixed to the chemical liquid bottle 2 by the pressing portion 229. As described above, the plug member 218 can be easily attached to the chemical liquid bottle 2 simply by inserting the air nozzle 220 into the chemical liquid bottle 2, covering the mouth portion with the stopper 219, and sliding the bottle stopper 227. be able to.

After the plug member 218 is mounted, the barcode attached to the outer peripheral surface of the chemical bottle 2 is read with a barcode reader. As a result, the data stored in the storage unit 89 is referred to, and information related to the corresponding drug (name of drug, code number, etc .; hereinafter referred to as drug solution information) is called and written in the RFID 225.

Subsequently, the shutter 165 is slid to expose the attachment / detachment space 163. By sliding the shutter 165, it is possible to secure a wide area that opens not only on the front side of the apparatus main body 161 but also on the side side, and that allows easy access to the attachment / detachment space 163. This is only when the chemical bottle 2 supported by the rotation support portion 168, the lock mechanism 186, the moving member 253, the second pressing member 254, etc. are arranged above the annular support 167 and the chemical bottle 2 is replaced. This is because the rotation support portion 168 is rotated to move the chemical liquid bottle 2 to the attachment / detachment space 163 below the annular support 167. Therefore, in addition to the attaching / detaching operation of the chemical liquid bottle 2 described below, cleaning of the attaching / detaching space 163, other maintenance, and the like can be performed smoothly.

And the chemical | medical solution bottle 2 is each mounted | worn to each rotation support part 168 of the cyclic | annular support body 167 in the state which exposed the attachment / detachment space 163. As shown in FIG. In the mounting of the chemical liquid bottle 2, the lock member 204 is operated to bring the rotating portion 171 into the unlocked state, and then the rotating drive portion 185 is moved (the second motor portion 189 is driven to move the first motor portion 188). The intermediate gear 200 of the rotation drive unit 185 is engaged with the driven gear 176 of the rotation support unit 168. Then, by driving the first motor unit 188, the first drive gear 199 is rotated and the driven gear 176 is rotated via the intermediate gear 200. Thereby, the rotation part 171 of the rotation support part 168 rotates from the attachment / detachment preparation position to the attachment / detachment position.

If the rotation part 171 rotates to the attachment / detachment position, the chemical solution bottle 2 to which the plug member 218 is attached is attached. At this time, the storage unit 89 stores the chemical information stored in the chemical bottle 2 to be attached and the attachment position ID of the rotation support unit 168 of the rotation unit 171 located at the attachment / detachment position. The

In the dispensing process, based on the chemical solution information of the prescription data received from the server, the data table of the storage unit 89 is inquired, and the chemical solution bottle 2 in which the corresponding chemical solution is stored is specified from the associated mounting position ID. And the corresponding chemical | medical solution bottle 2 is moved to the extraction position by rotating the cyclic | annular support body 167. FIG. In the rotation of the annular support 167, position information that associates the rotation position with the positional relationship of the chemical liquid bottle 2 supported by each rotation support portion 168 is stored, and the annular support 167 is rotated based on the position information. What should I do? Further, an RFID reader / writer may be provided at the extraction position and the RFID 225 may be read to identify the position of the rotation support 167.

Subsequently, the bottle placing portion 60 on which the patient bottle 6 is placed is raised, and the upper opening thereof is positioned in the vicinity of the fourth tube connector 252. Further, by driving the slide motor 255, the slide base 256 is advanced, and the second pressing member 254 is positioned at a predetermined position with respect to the rotation support portion 168. At this time, the rotation shaft of the rotation motor 270 provided on the second pressing member side is positioned in the positioning recess 224 formed in the spacer 178 on the rotation support portion side. Further, the air nozzle 220 enters the guide recess 238 of the plug 219 and is connected to the communication hole 234. Further, the pressing plate 269 presses the pressure receiving piece 239 and rotates it to release the second tube 236 from the crushed state.

Next, the rotation motor 270 is driven to rotate in the reverse direction, the cam 271 is rotated in the reverse direction, and the pressure receiving portion 248 is pressed by the pressing roller 273, thereby rotating the first link plate 246. As a result, the pressure receiving roller 249 is pressed by the lower edge of the first link plate 246 to rotate the second link plate 247, and the first pressing member 223 integrated with the second link plate 247 becomes the first tube 221. Separate from. By maintaining this state, the chemical solution in the chemical solution bottle 2 is continuously supplied to the patient bottle 6 via the first tube 221. The supply amount of the chemical solution to the patient bottle 6 is performed based on the weight detected by the bottle mounting unit 60 until the first set value before reaching the desired supply amount (dispensing value).

At this time, the supply of air into the chemical liquid bottle 2 may be performed so that the inside of the chemical bottle 2 is maintained at a constant pressure based on a detection signal from the pressure sensor 266 or the like. The internal pressure may be gradually increased so that the discharge amount does not decrease with the decrease.

When the supply amount of the chemical liquid to the patient bottle 6 reaches the first set value, the rotation motor 270 is driven to rotate forward, and the cam 271 is rotated forward. As a result, the second link plate 247 is returned to its original position by the urging force of the spring 250, and the first tube 221 is once pressed by the first pressing member 223 to block the flow path. When the cam 271 further rotates forward, the pressing roller 273 integrated therewith rotates and rolls while pressing against the first tube 221 from the upper side toward the lower side. As a result, the chemical liquid that has remained in the first tube 221 on the lower side of the position pressed by the pressing roller 273 is pumped downstream. In the middle of this rolling, the pressing portion 274 formed on the cam 271 contacts the pressing receiving roller 249 of the second link plate 247 to rotate the first link plate 246. As a result, the first pressing member 223 is temporarily separated from the first tube 221, and a certain amount of the liquid medicine thus pumped flows down to the patient bottle 6 via the fourth tube connector 252.

Hereinafter, the cam 271 continues to rotate in the forward direction until reaching the second set value that is closer to the dispense value than the first set value, and the drug solution is dispensed into the patient bottle by a certain amount. If the detected value becomes the second set value, the rotation speed is suppressed by reducing the voltage applied to the rotation motor 270. This is to eliminate variations in detection values caused by dispensing the drug solution into the patient bottle at a relatively high speed even intermittently. In a state where the detection value is stable, a certain amount of chemical solution is supplied, and when the dispensing value is reached, the driving of the rotation motor 270 is stopped.

Although not employed in the third embodiment, air is supplied in the middle of the chemical liquid flow path from the chemical liquid bottle 2 to the discharge port of the first tube 221 to block the flow of the chemical liquid. Also good. That is, as shown in FIG. 42, an air supply path communicating with the air nozzle 220 is formed in the vicinity of the lower end opening (discharge port) of the air nozzle 220. Then, when the liquid injection operation is completed, air is supplied into the air nozzle 220 through the air supply path. This air is, for example, air after being cleaned or inert gas. As a result, the chemical solution does not directly touch the surrounding atmosphere, and contamination is prevented.

In addition, as shown in FIG. 43, the stopper 219 is preferably provided with an auxiliary guide part 275 that guides the body part and the bottom part of the chemical liquid bottle 2 in a rotatable manner.

The auxiliary guide portion 275 is provided on the stopper 219 so as to be rotatable about the shaft portion, and has a lattice-shaped side surface portion 276 that guides a part of the outer peripheral surface of the chemical liquid bottle 2 and a bottom surface that guides about half of the bottom surface. Part 277. Similarly to the bottle fastener 227, the auxiliary guide portion 275 is not screwed to the concave portion 224 of the stopper 219 to an appropriate position, similarly to the bottle fastener 227. The bottom surface portion 277 cannot rotate to a position where it guides the bottom surface of the chemical liquid bottle 2. Therefore, it is possible to detect whether or not the screwing state of the chemical liquid bottle 2 is appropriate also by the auxiliary guide portion 275.
